TL;DR: Taenite is a main entry in the 外星矿物知识引擎 database.
Taenite is the high-nickel phase of iron meteorites, intergrown with kamacite to form the distinctive Widmanstätten pattern. Its nickel content makes it valuable for stainless steel production in space.
Formula
Fe₀.₅Ni₀.₅ to Fe₀.₂Ni₀.₈
Crystal System
Cubic (face-centered)
Occurrence
Intergrown with kamacite in iron meteorites; Widmanstätten pattern; M-type asteroids
Significance
Higher nickel content than kamacite; source of nickel and PGMs; indicator of slow cooling in parent body cores
